This is a great find! Its the1955 Chevrolet Nomad form the Johnny Lightning, The Fabulous Motorama series.

It's a great find because they only made the  Motorama series for one release which was 20+ years ago in 2002. 

Top that off with the fact that it's a Nomad and you have one very collectible, sought after car in a very unique color (1:64 Scale)
